[Clang] Define `__WCHAR_MIN__` and related macros (#208135)
Define `__WCHAR_MIN__`, `__WINT_MIN__`, and `__SIG_ATOMIC_MIN__` for
compatibility with GCC.
This also fixes targets such as `riscv*-netbsd` that define `WCHAR_MIN`
from `__WCHAR_MIN__`.

Closes #199678

- Fixed assertion failures involving code completion with delayed default arguments and exception specifications. (#GH200879)
- Fixed a regression where calling a function that takes a class-type parameter by value inside `decltype` of a concept could be incorrectly rejected when used as a non-type template argument. (#GH175831)
- Fixed a crash in the constant evaluator when an ill-formed array new-expression whose bound could not be determined (e.g. `new int[]()`) was used in a constant expression. (#GH200139)
+- Clang now defines the GCC-compatible predefined macros `__WCHAR_MIN__`, `__WINT_MIN__`, and `__SIG_ATOMIC_MIN__`. (#GH199678)
